Model Description


2 Strokes ahead.

Some races are won before the gate even drops, and the latest YZ125 gives you the edge to do that. Yamaha has been building and racing 2-stroke motocross bikes for over 50 years and it is this unrivalled experience that has enabled the company to once again further improve the latest YZ125 – making it a bike that is built to take you to the top of the podium.

Getting the best out of your bike at every situation is crucial to winning a race and the latest YZ125 makes it easier than ever to do that. With the update to the intake system, the bike is more responsive in cornering and smoother on corner exit as you accelerate and work through the slick-shifting close-ratio 6-speed transmission, all the way to victory.

The lightweight race-bred engine internals and Yamaha’s famous torque-boosting YPVS (Yamaha Power Valve System), ensure hard-hitting power, while the ultra-slim bodywork gives you a high degree of controllability on the ground and in the air. When you are braking and accelerating hard, the flat seat and race-developed ergonomics allow you to move easily around the bike as you enter the victorYZone!
